sEPAaATING OIL-cans.

To all whom t may concern:

Be it known that I, ALEX E. A MaNs, al citizen o f the United States, res1d1ng at `Seattle, in the county-of King and State of l/lfashington, have invented certainnew and usefu Improvements in Separating Oil-Cans, of which the following is a speciiication. i

This invention relates to an improvement in machines for separating metallic ca ns from the wooden receptacles or boxes in which they are shipped. v f lt is customary to protect metallic coni tainers of this type in wooden cases, and

is, therefore to provide a machine for removing the metallic cans from rsuch wooden cases, with the destruction of as little of the wooden case as possible, and with the minimum of labor and expense in the operation., .Y

The invention will be described 1n the following specification, with `particular re f-.

accompanying drawings, 1n

erence to the which l Figure l is a 4plan of the impro-ved machine, the top orV cover section being removed.

The improved machine comprises a main frame( 1, made up of base stringere 2, and table stringers 3 supported Vfrom the base stringers by uprights 4.

Arranged between the table stringers 3, at each end of the machine, are belt rollers 5, over which endless belts 6 are adapted to travel. These belts, which aside from the details noted, may be of any structure, are

spaced apart to just receive the side edges of the wooden case, shown at 7, in'which the cans 8 to be removed, are packed.

vThe belts when so arranged provide a central open space 9, somewhat less in width than that of the wooden case 7, but

Vsuiicient in width to permit the cans 8 to pass therethrough. Flights 10 are arranged on the belts, for compelling travel of the box with the belts.

At the entrance end of the machine, and

. to one side thereof, is arranged a revolving upright shaft 11, having radial arms 12 at 4the upper end thereof, to engage and initially movethe wooden case and contained cans onto the belts. If desired, and as preferred, a feeding means may be provided for delivering 'the lled cans to the machines,

such means 'being here shown as .suitably t having ights 14, and on which the filled cases are placed byhand for delivery, to the machine.

This initial feeding means is preferred, as thereby the cases may be delivered to the machine in properly timed order as will be later apparent.

The full length of the machine is protected above the table stringers 3 by an inclosing section or cover I15, having side walls and a top. The side walls are spaced apart to just permit the case to move therethrough, whereby the case is guided and held true in travel.

Splitting knives 16 and 17 are arranged in the path of travel of the case. an upper set 16 being secured to the top of the cover section 15, and the lower set 17 secured to a cross bar 18 arranged on the main frame. The knives v16 and 17, which are eoual iu cutting depth-to the thickness of the top and lbottom boards of the'wooden case 7, are designed as the case is fed forward, to split the top and bottom of such case into narrow strips. The usual metallic corner binders of the case are also cut by the knives.

A clearing member is arranged in rear of the splitting knives, such clearing member comprising a bar 19, secured to the frame and arranged in the path of the bottom of the case, and 'a similar bar 20 secured to the cover and arranged in the path of travel of the top of the case. Springs 21 are arranged in advance of the bar 19 to initially receive the impact and cushion the same.

The wooden cases in their delivery to the belt 6 are timed so that each case will be taken up by the flights 10, and the Ycases forced past the knives 16 and 17, after which the clearing members serve, as the V clearing members is arranged the can remover, comprising a hammer head 22 of a size to fit in the case to engage both cans therein. This hammer head is carried on an arm'QB, pivotally supported on a side post 24, and is operated through a suitably driven wheel 25, having cam projections 26.

`These projections successively engage beneath a lug 27, depending from the arm 23, so that the hammer head is raised and allowed to drop at regularly timed intervals. As the open case is delivered beneath the hammer head, the latter just previously raised, is permitted to drop, forcing the cams from the case onto la suitable bed through the opening 9 in the belt 6.

rThe cans are thus removed from the cases ina continuous simple operation, and the sides and ends of the wooden cases are kept together and in original shape for reuse.

The case is next discharged from the leading end of the belts 6.

Claims 1. A machine of the class described, comprising an endless conveyer for the cases, means arranged in the path of travel of the case to split the top and bottom portions thereof, means to remove the split portions, and means to force the contentsof cases therefrom.

2. A machine of the class described, com prising endless conveyers to carry the cases and spaced apart at less width than the cases, means for splitting the tops and bottoms of the cases, means'for subsequently interrupting the travel of the split portions of the casesto force such split portions between the conveyers, and means for finally forcing the contents of the cases between the conveyers.

3. A machine of the class described, comprising 'a case, conveyers spaced apart and above which a case is positioned, a cover in` closing the conveyer and guiding the cases in travel, upper and lower splitting knives arranged in the path of travel respectively of the top and bottom sections of the case,

means operating subsequently to the knives prising a case, spaced conveyers above which a case is positioned, a cover inclosing the conveyer and guiding the cases in travel, upper and lower splitting knives arranged in the path of travel respectively of the top and bottom sections of the case, means operating subsequently to the knives for removing the split portions of the case, a hammer to force the contents of the case between the conveyers, and a cam wheel for periodically raising the hammer and freeing the same for gravital movement.

5; A machine for removing cans from wooden shipping cases, comprising a frame, endless conveyers operating thereon and spaced apart of less width than that of the case, means on the conveyers to move a case therewith, a cover above the conveyer to accurately guide the case inV travel on the conveyer, splitting` knives for the'top and bottom sections of the case and supporting respectively by the cover and frame, clean ing barscarried by the cover and frame to engage the split top and bottom of the case in the travel of the case and force such split portions betweenthe conveyers, and a ham- Y mer operating through the case following the action of the clearing bars to force the contained cans between the conveyers.

6. In an article'of the classdescribed the` combination lof a frame work, conveyers upon the same adapted to convey wooden can containers, said conveyers being spaced apart a distanceless than the Vwidth of the Y containers, a cross-piece on the frame and springs on the cross-piece against which springs the said containers are ladapted to contact, a cross piece on the chute, the said ,cross-pieces being of substantially the same thickness as the top and bottom boardsV of the container, whereby when the container is forced against the said cross-pieces the top and bottom thereof will be forced from the container, 'a trip hammer, and means for operating the hammer to deliver a blow from the same upon the exposed cans.

In testimony whereof I aiiiX my signature.
